COMPOSITlON OF MATTER TO BE USED AS FUEL AND PROCESS OF MAKING SAME.

Specification of Letters Patent Arplication filed 6. 1906- Be it knownthat I, EDGAR L. OULVER, a citizen of the U nited States, andI'OSltllIlfJ, at 1 South Omaha, Douglas county, brasira, have invented anew and useful Composition of Matter to be Used as Fuel and 1 Process ofMaking theSa-ine, of which the following is a specilication.

This invention relates to artificial fuel and process of making same,and has especial reference to employment of manure as a principalingredient and of working it up in a manner so that the offensive odormay be removed, during manipulation, as will be explained.

The invention includes the p'rocessiof male ing the fuel as well as thefuel itself.

Raw manure is first gathered and run through chopping; and tearingmechanism until it is thoroughly disintegrated, and then passed throughan evaporator l.)eiu,e thereby entirely dried, and dropped from theevaporator into the mixer, the granules of manure during this movementbeing substantially enveloped ing in a manner so that themanure-granules and coal tar thereafter adhere, the mass, after thistreatment having no odor of manure wl'iatever; there is no objection tothe use of rotted manure in this connection, but the inventioncontemplates the use of raw manure, which, as is well known, has novalue as a fertilizer, and which may be gathered in large quantities ator near stock-ya rd centers at very slight expense. Whether raw orrotted manure is used, the combination after the manure-granules havebeen covered or sprayed with liquid coal tar, is perfectly odorless,unless it be a slight trace of the odor of tar.

The mixer is provided with a receptacle adapted to hold liquids as wellas solids, and pulverized hard or soft coal, clay, water, chlorate ofpotash andsaltpetre is then added, the chlorate of potash and saltpetrebeing dissolved in water before being, added. miring, is very thorough,the amount of water State of Newith coal tar as by spray-- The 1 beingsullicient to lubricate the clay so tha t coal, chlorate ol' potash,szltpetre, water and it will be plastic", the coal tar and manure, aswell as the pulverized coal become (llStl'llh the mixing process.

1. find it to be of advantage to employ per cent of manure, 5 per centof coal tar and 10 per cent of pulverized coal, and to use 2 pounds ofsaltpetrc and l. l

,pounds of chlorate of potash to the ton', but this may be varied byreducing the manure to as low as 30 per cent and increasing the coal to40 per cent and increasing the coal tar used to 30 per cent, if a morerapid cornbustion and consequent quickerhcat is desired.

Artificial fuel, by employing the above ingredients, and prepared in themanner described has been found to be entirely practical, even when 85per cent of manure is used. The coal tar entirely removes the odor ofthe manure from the time they are united and no odor of manure isperceptible when the product is completely formed or when delivered tothe consumer, or during combustion. The slight trace of tar odor is notnoticeable.

After passing the mixer the combined 'ingredients are exposed toheatuntil thoroughly dried, and the product is then ready for use as fuel,but is preferably formed into briquots for the trade, before drying. Thewater'and clay operate as binders, the water being evaporated, stated,before use. The saltpctre increases the amount of heat derived, and thechlorate of potash causes formation of oxygen-gas which, combining withother gases,

renders the combustion more complete; the chlorate of potash and clayalso diminishes, during combustion, the amount of smoke given off fromuse of ])l1l\'0ll' "I-;l coal, this bc ingthe result where either softor hard coal is utilized.

This artificial coal has met with favor for stoves, ftn'naces, and forproducing steam in mamd'actories, and has a usefulness since it bringsinto use the valueless item of raw manure, as already explained. I orcertain uses of this fuel product, the amount of saltpetre and chlorateof potash may be increased to advantage, and'i do not limit myself tothe exact quantities given. I i
